Solution
1. Preparation
  • Gather tools and materials: OBD-II scanner, power steering fluid, wrench set, fluid catch pan, and rags.
  • Ensure the vehicle is on a flat surface and the engine is cool.
2. Check Power Steering Fluid
  • Locate the power steering fluid reservoir (refer to the owner's manual if necessary).
  • Remove the cap and check the fluid level against the markings on the reservoir.
  • If low, top off with the recommended power steering fluid (refer to the owner's manual for specifications).
3. Inspect and Replace Fluid
  • If contamination is found, drain the old fluid using a fluid catch pan.
  • Refill with fresh power steering fluid.
  • Run the engine and turn the wheel from lock to lock several times to circulate the new fluid.
4. Inspect Power Steering Pump and Hoses
  • Check for any signs of leaks around the power steering pump and hoses.
  • Tighten connections if any are found loose; replace any damaged hoses or the pump if necessary.
5. Test Power Steering Pump Pressure
  • Attach a power steering pressure gauge to the pump outlet.
  • Start the engine and check pressure readings against manufacturer specifications (refer to the service manual for exact values).
  • Replace the pump if the pressure is below specifications.
6. Steering Rack Inspection
  • Safely lift the front of the vehicle and support it on jack stands.
  • Visually inspect the steering rack for leaks or damage.
  • Check the tie rods for wear; replace if necessary.
